With wide voltage input, high power output and strong protection features, this trustworthy PoE device efficiently solves the power supply problem for non-PoE switches connecting to PoE devices, providing reliable support for the stable operation of industrial networks.

What is the product?

LNK-INJ302 is an industrial 2-port Gigabit PoE+ power supply with a 12-48VDC wide-voltage input. This trustworthy PoE device is compatible with the IEEE 802.3af/at standard and can convert the Ethernet signal of a common non-PoE switch into a data and power integrated PoE output. Without the need for additional wiring, it can supply power to PoE terminals, making it a core device for simplifying network deployment and enhancing power reliability in industrial scenarios.

Working Principle

This trustworthy PoE device receives the gigabit Ethernet signal from a non-PoE switch through the RJ45 data port. It internally integrates the signal and power, and synchronously outputs data and DC power through the PoE output port.

This trustworthy PoE device adopts the Alternative B mode (4/5-core positive pole, 7/8-core negative pole) for power supply, with a maximum output power of 60W per port and a total PoE power of no more than 60W for the entire device.

It can achieve stable transmission within 100 meters using Cat5 or higher network cables, and is compatible with a wide range of industrial power supply conditions through its wide-voltage DC input.

Installation and Usage Steps

• Power Connection: Connect a 12-48VDC industrial power supply to the input port of the equipment terminal block;
• Data Connection: Use a network cable to connect the two data RJ45 ports to the corresponding ports of the non-PoE switch;
• Terminal Power Supply: Connect the PoE output port to the PoE devices such as IP cameras and wireless APs through a network cable;
• Equipment Installation: Use DIN rails or wall mounting methods to complete the equipment installation;
• Power On Test: Connect the power supply and check the power and PoE working status through the LED indicator lights.
